Happy Wednesday all! First cables post of the year (I believe). Wow! Lots to catch up on! I liked chads ces post - a few years back I was able to go with a friend who owns a local electronics shop (from whence I am fed my klipsch addiction at a good price...), and I was a kid in a candy store. For my own untrained but enthusiastic ears however, I did learn of the laws of diminishing returns in AV gear as the $98,000.00 turntable did not constitute a religious experience for me and for the total cost of the cable risers, uber cables, amps, etc it should have been a watershed moment. My ears need much more training I suppose. Have a great hump day!

Congrats Chuck. First time I saw you here I said to myself...."now that guy has some things to say". Jake says "woof" to Baxter.

Maybe he'll promote taco wednesday Everyday can be taco day…..they're that good!

Spoke too soon. Mark has arrived. The Weather Witch here tells us with a sense of urgency and alarm that the nice, warm weather the past few days will soon be gone and another snow front will be upon us. Shocking for Colorado in January. Bunch of odds and ends to take care of. Will try to check back. As usual, cheers.

Espresso for me, with a squirt of white chocolate syrup and a splash of carmel macchiato creamer. The other guys at the shop like a light roast or medium roast, black and strong. Usually a Breakfast Blend, Ethiopian, or 8'o'clock.

speaking of hump day, i came across a pic of a cactus that my (lesbian) sister gave me. it was really funny because she is so anti-male and shy. i could just picture her in line at lowes with this cactus. we had this cactus in the shop office for years. had been offered sums of money for it. nope -- my cactus. and then it began to wilt...

Been here for an hour, diod i miss something? Ansering Pms, fetchin coffee......

And yet no mention of tacos?

Evening gang Back from farm, up from Nap. Cold, wet, and Skeeters. Wife had a great day visiting the indians As i predicted, she paid for the experience Farmer that crashed his 18 wheeler over the cliff an xmas is doing fine. Every one there say's he is One Crabby azzhole. hell that alone tells me he is fine Bench project, scope shopping. Taco time

NO, cats don't belong in a pile of scrap! What's wrong with you?

Missed so much around here I need to catch up. Glad to be back home and back to what we call normal, so far all I have done is drink coffee today.

We'll determine whether or not your whining, thank you very much.

Oh my, that's a prickly situation --

Haha….that's hilarious! Iv'e heard there's a cure for that

Mornin' all. Hey...where's everybody at??

Good "PowerBall" Morning Gang 46, wet, and the weather Drama queens have informed us Deadly "Wind" of 10 to 15Mph may be coming Coffee should be done, then maybe i can think of the day........

While I understand that some have reservations, my son and I enjoy the range; first rounds on this piece this weekend. Hope the CZ gets here as the shipper is 'delayed'

Congrats…but it's hard to forget tacos!

Forget the tacos ... it's 1K Posts Tuesday!! Happy 1K Posts Tuesday!!!

Now you get the ridicule without benefits.

I am on Michael Rays side on this! The above statement ^^^^^^^^^^^ is an obvious example of complaining or belly aching depending on where you come from. Now what Michael Ray did in Hope last year, well "THAT" was a clear example of whining! !! I wanted to buy some chocolate and Midol for his mangina!

Oh well, was a nice thought since not everyone is always listening to that one track they think defines them.

Nothing worse than a wilting cactus prosthesis if you ask me.

My car already has a horn.

No way.

Oh how the mighty have fallen...

It happens.......................... Usually it's someone else's fault though. It's the preferred method by far.

That's funny, but after years it can happen, just leave it for a little while and then show it some attention and it will be fine.

Haha….that's hilarious! Iv'e heard there's a cure for that Yeah, pills. Farmers must really like them, comes up in their conversations all the time. Been offered them many times, no need, as of yet, as far as i know........

Some new 18's. Because I'm narrow minded like that. Currently in the process of converting them from the stormtrooper model to darth vader (black). Should be thumping by the weekend.

and also:

He's 16 and lives in an apartment with his mother and sister. I would be surprised if ripping out the drywall would be appreciated by the landlord! Think "moderate temporary room treatment" and "economical." Big fluffy pillows on top of the wardrobe, per his picture in Post #1? Just my guess.

NO, cats don't belong in a pile of scrap! What's wrong with you? I guess I should have said UNDER a pile of scrap

Yep, got it in 3 Min.

There is a black/white cat in this picture. Where is it? LOL.

Congrats Chuck. Now you're 20% of the way to admission to the BS secret forum I'm nearly 80% of the way to eligibility, but I have no plans to go there. To paraphrase Groucho Marx, I don't want to belong to any exclusive club that would have me. :-))

Congrats on 1K Chuck!

Good afternoon Gang Drizzle day here, but at least it's 52. Home from Gunsmith/farm/Gunsmith. Gloomy Monday, and likely be this way all week, no real weather. Bench Project(s), shop the Bay for a bit, dam farmer(s) Do keep me sharp on shopping. Im finding between my projects and keeping them in toys, im actualy busy

One more post Chuck and your at 1000, Congratulations

Yeah ...that guy can really move a team when healthy.

More like pleading.

Well Cup Cake Chimes in. Welcome to the new year, i hope it is more furitfull than you're last

We'll determine whether or not your whining, thank you very much. Yep, i call on that statment myself.

If I may comment. We want high acoustic efficiency so that the diaphragm of the woofer does not move much, but still pumps air. Movement itself will cause new frequencies to be created which is called Doppler distortion. This is like the whistle on a train as it goes by. You hear the change in pitch, or a new frequency. There are other distortion products in the mix. What to do? PWK explains that if you have a piston moving in a lake, it doesn't pump much water, but put the piston in a cylinder, it can pump water. The water can not run away to the sides. Similarly, when the piston diaphragm is coupled to a tube, it pumps more air with less movement. This is called a higher acoustic impedance on the driver diaphragm. But if we are pumping air into a tube, what happens at the other end of the tube. Actually, the air at the other end encounters what I'll call, non-trapped air, which was our problem to begin with. What to do? We allow the horn to gently expand in area as we go down the length. One widely recognized expansion is called "exponential." There is a complicated "exponential equation" to describe this. But suffice to say, the area doubles every x distance down the horn. In the K-Horn, LS, and Belle we start with a tube (throat of the horn) about 0.5 square feet (at a high air pressure) and allow it to expand to 4 square feet. At higher freqs this horn acts like the tube. However now we have a big end (mouth of the horn) where the air pressure has reduced and acts like a diaphragm of 4 square feet. Essentially we have the effect of a much bigger piston than we started with even though there no diaphragm at the mouth, only air, there. The horn does not act like a tube at low freqs and this point is described as frequency cut off or fc. There is no longer the higher acoustic resistance which helped us so much. Even worse, at low freqs the air in the horn starts acting like a slug of air and just moves back and forth. Therefore the speaker motor has to do work moving the clumped mass of the slug of air instead of pumping sound down the horn and out the mouth of the horn. (Having to move the slug of air bogs down the speaker motor just where, in freq, we're already hurting from lack of acoustic impedance. The double whammy.) What to do? We can put a chamber behind the driver which acts as a spring. There is a resonance formed by the slug of air (mass) and the spring. This is called "reactance annulling." There is another problem at high freqs. The moving mass of the speaker driver (diaphragm and voice coil) has to be moved by the electrical motor. The higher the freq, the faster it has to be moved. This requires some higher math. I think of it as heavy sleigh on ice. If you want to move it back and forth at a low freq, it is not much work. But if you move it back and forth at a high rate, it is lot of work to get it started forward, stop it, move it backwards, stop it, move it forward. etc. You are actually moving the sleigh faster in each cycle as frequency of the cycle increases. That is acceleration. (Remember Force = Mass times Acceleration. Having to move the mass bogs down the speaker motor.) What to do? Mass is the problem again and we have to find another spring. With our sleigh, it would be nice if we had a spring attached to it (forward and back) so that that the mass will oscillate at the high freq. In the horn, we put a small chamber in front of the diaphragm. But wait, the diaphragm has an area of about 1 square foot and the small end of the horn attached to the other end of the front chamber is 0.5 square feet. That is not much of a chamber. What to do? This is not explained well but I believe that PWK put in the restriction of a 3 x 13 inch slot to partially seal off the horn side of the front chamber.

Good Tuesday Morning gang Real water from the sky is taking place, maybe a 1/4". Drama weather people are all evcited this morning. I see on the morning news here all freeways are 50Min slow down. Retraining for driving in wet conditions is now in effect. Taco Tuesday and a Farm run as well as Breakfast Burrito from the Farm Deli Wife feels the need to enhance the local Indian(s) welfare donation for her Xmas present. RedHawk Casino, just outside placerville. Food sucks. Desserts suck, so i refrain from trip. Ah, i see in the CCTV wifes garage, she is UP........

take it from someone who switches his living room gear around every few months. about once a year i decide i dont need such big stuff in my living room and keep going back to small stuff. buy small stuff then 3 months later I'm selling and going back to big stuff cause i just can't get over the small sound. now, if you had a dedicated theater with rf-7 setup and was talking a 50" over a fireplace then id say sure to keep it nice looking and you have another setup in a different room. but if this is your only setup, you aren't gonna want that 75" new tv having dinky sound to accompany it. i say buy some wire track and run it along your baseboard and you won't even notice it then you dont have to run any new wires in wall. problem solved and you get to keep your amazing blow your hair off setup.

It was odd watching Manning coming off the bench, but he did well. I'm glad everything is back to normal, kids back at school, wife back at work….I know they all wanted to go back Cold here today and tomorrow, then to the upper 40s later in the week.
